python: cpython: CPython: tarfile extraction filter bypass allows escaping the destination directory

A flaw was found in the tarfile.extractall function within Python. A remote attacker could exploit this vulnerability by providing a specially crafted archive. This archive could bypass security filters by using a hardlink that references a symlink, allowing the symlink to be recreated outside th...

Astra Linux – Vulnerability in Firefox

Uploading files that contain symlinks may have allowed an attacker to trick a user into submitting sensitive data to a malicious website. This vulnerability affects Firefox 115...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2. When reading data from a jfs filesystem, grub’s jfs filesystem module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size. However, it improperly checks for integer overflows. A maliciously crafted filesystem may cause...

Astra Linux – Vulnerability in php-pear

In ArchiveTar before version 1.4.14, symlinks can reference targets outside of the extracted archive. This is a separate vulnerability from CVE-2020-36193...

Astra Linux – Vulnerability in Python 3.11

It allows the extraction filter to be ignored, enabling symlink targets to point outside the destination directory, and modifying some file metadata. This vulnerability affects users who use the TarFile module to extract untrusted tar archives using TarFile.extractall or TarFile.extract, with the...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ocfs2: Properly handles errors when reading symbolic links. It’s a patch from the “Convert ocfs2 to use folios” series. Mark converted ocfs2 to use folios and sent it to me as a major patch for review ;-. So I reworked it into...

Astra Linux – Vulnerability in oddjob

A race condition was identified in the mkhomedir tool included with the oddjob package in versions prior to 0.34.5 and 0.34.6. During the home creation process, mkhomedir copies the /etc/skel directory into the newly created home directory and changes its ownership to the home’s user, without...

Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system for Linux and other Unix-like operating systems. In versions 2.4.8 and earlier, when starting the cupsd server with a Listen configuration item pointing to a symbolic link, the cupsd process could perform arbitrary chmod operations on the target...

Astra Linux – Vulnerability in node-tar

The npm package “tar” also known as node-tar in versions prior to 4.4.16, 5.0.8, and 6.1.7 has vulnerabilities related to arbitrary file creation/overwriting and arbitrary code execution. node-tar aims to ensure that any file whose location would be modified by a symbolic link is not extracted...

Astra Linux – Vulnerability in open-vm-tools

A issue was discovered in open-vm-tools 2009.03.18-154848. Local users can bypass the intended access restrictions on mounting shares through a symlink attack that exploits a realpath race condition in mount.vmhgfs also known as hgfsmounter...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2. When performing a symlink lookup from a romfs filesystem, grub’s romfs filesystem module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size. However, it improperly checks for integer overflows. A maliciously crafted...

Astra Linux – Vulnerability in avahi

The avahi-daemon-check-dns.sh script within the Debian avahi package, as of version 0.8-4, is executed as the root user via /etc/network/if-up.d/avahi-daemon. This script allows a local attacker to cause a denial of service or create arbitrary empty files through a symlink attack on files located...

Astra Linux – Vulnerability in sudo

The “sudoedit” personality of Sudo before version 1.9.5 might allow a local unprivileged user to perform arbitrary directory existence tests by exploiting a race condition in the “sudoedit.c” code, which allows a user-controlled directory to be replaced with a symlink pointing to an arbitrary pat...

Astra Linux – Vulnerability in RustC

Rust is a multi-paradigm, general-purpose programming language designed for performance and safety, especially safe concurrency. The Rust Security Response WG was notified that the std::fs::removedirall standard library function is vulnerable due to a race condition that enables symlink creation...

Astra Linux – Vulnerability in imagemagick

ImageMagick is free and open-source software used for editing and manipulating digital images. Before versions 7.1.2-16 and 6.9.13-41, authorization based on the "domain=" path was checked before the final file could be opened or used. A symlink swap was used to bypass the policy-denied read/writ...
